I have a forward setup on one of our public facing email addresses to a few users outside of our system (to an external address). Seeing as it's public (printed on a website in plain text), we get TONS of spam on that account. We're being marked as a SPAM source due to the forwarding by the external system. We have pretty aggressive IMF (Intelligent Message Filtering) setup, and it works great for internal messages. The problem we're facing is that Exchange is forwarding ALL the email received on that account, and not just the messages that pass the IMF (and don't get pushed into Junk).

As far as I can tell, there's no way to adjust the IMF settings for that one account. And as far as I can tell, there's no way to setup folder forwarding (inbox -> external address) from Exchange. Is there something I'm missing or is there any way around these issues that I may be missing?

Thanks...
